simplified render_to_response with RequestContext

manything need to do with RequestContext, but it's too tedious.
use
render_to_response("/my.html", {'key':value,},request)
instead of
render_to_response("/my.html", {'key':value,},new RequestContext(request))
and you can also use
render_to_response("/my.html", {'key':value,},new RequestContext(request))
